'He was awesome' Cousin remembers trucker involved in Interstate 95 collapse in Philly

PENNSAUKEN, New Jersey (WPVI) -- Sources and family members have identified the driver of the truck that crashed and caught fire underneath an overpass, causing the collapse of several northbound lanes of Interstate 95 in Philadelphia.

They say Nathaniel Moody was behind the wheel of the tanker truck when it crashed around 6 a.m. Sunday in the Tacony section of the city.

While his death hasn't been officially confirmed, family members believe human remains found at the scene are those of their loved one.

They say Moody worked for TK Transport in Pennsauken, New Jersey. They say he was an experienced truck driver.

His apparent death has been a devastating blow.

Sources have identified the driver of the truck that caught fire before a portion of Interstate 95 collapsed.

"He was awesome. He was awesome," said his cousin, Isaac Moody, while fighting back tears.

Isaac Moody says his cousin was his best friend.

"I wasn't expecting this. Nobody was expecting this," said Isaac Moody.

He said the family was told by Pennsylvania State Police that a final identification of the remains in the I-95 wreckage will be done through dental records.

The fire was so big it had overtaken both northbound and southbound lanes on the highway, witness Lisa Taormino, who was commuting southbound on I-95 about 20 minutes before it collapsed, told ABC News.

The family had hoped Nathaniel had escaped and would turn up at a local hospital. It never happened.

Nathaniel Moody leaves behind his longtime girlfriend and a 7-year-old daughter, who was the center of his world.

"I don't know what I'm going to say to her when she says 'Big Cuz, do you see my daddy? Do you know where my daddy is at? Can you find my daddy?'" Isaac said. "I don't know what I am going to say to her."

Isaac Moody, a truck driver himself, says his cousin was a very experienced driver who worked overnight hours.

He says Nathaniel knew the dangers of driving and enjoyed working for TK Transport.

"There is so much that can go wrong with a fuel tanker. If you don't have this valve closed right, if this pressure is not right over there. Nate was very careful with that stuff," Moody said.

"We need this off-ramp shutdown. I have no idea what is on fire," an officer can be heard saying over the radio.

What went wrong is still under investigation.

The family will wait for answers but the grieving has already begun.

"I am kind of baffled. I am trying to not cry because I don't know what happened. I don't know what happened."
